We are doing a big DS ride this month with Coos Bay being our turn around. We are planning on hanging out in Coos for a full day and wanted to go out on the dunes. What is the deal with the flags? Are they manditory? Where can we buy them in town? We are not planning on ripping the dunes all day, we just want to ride on the beach a little. Also, what is required as far as ohv fees or stickers? We are all on plated Ca bikes. Side info: What are some cool "gotta see" (or do) in Coos? My buddy is judging a BBQ cook off at the casino, but the rest of us are free for the Saturday. I'd like to ride out to the ship wreck N of town I heard about. Other than that, we will be lost in Coos for a day. Thanks for the tips.
